Application vtiled April 15, 1910. Serial No. 555,734.

To all whom 'it may concern:

Be it known that WILLIAM Lucian` BATEN, a citizen of the-United States, and a y hitherto constructed, sofar as `I am aware,

are such as to pass the entire output fed to them from ,the saw, through the soda bath, and as it is unnecessary to dip much of the lumber, only about 30% in the usual run, the major portion lof the solution is wasted. In accordance with my invention, only such lumber` passes through the soda. tank or bath as determined b the operator or grader, the travel of each piece through the bath or over by-pass being controllable at his will.

` Reference is to b e had to the accompanying drawings forming a-part of 'this speci' ication, in whichtsimilar characters of reifer'-` ence indicate corresponding parts in all the views. n i 4 Figure 1 is a plan of a soda dip machine constructed in accordance with my inven-` tion; Fig. 2 is a cross-section of the same Fig. .3 is an end elevation of the machine partly in section; Fig. 4 is a sideview of a bell-crank lever forming anelement of the controlling mechanism; Fig. 5 is an edge view 'of the said lever 5' and Fig' isa frage v mentary inner face view of one'of the arms of the said levelii Arranged at the required elevation` on a suitable support or framework 10, is a horizontallydispose l open tank 11 for containing the soda bath, this bath being ordinarily a 10%solution of bicarbonate of soda,the tank being sufliciently long to receive lengthwise the longest lumber which is to. be

dipped vand heated bya steam coil 10a. Ex- 1 'tending longitudinally of the tank, substan# tially centrally thereof, is submerging roller 12, the roller being arranged rnear the bottom of the tank and having its .axle or' journals 13 at the ends, journaled in suitable bearings, which are carried by the end walls of the tank, or other supports arranged 'at or near these points, these walls or supports being elevatedslightly above the roller and carrying a by-pass for the lumber, which is in the nature of a downwardly and 'forwardlyinclined slide 14', the slide `at its lower end extending well over the side of the tank, and, as bestshown in Fig. 1, is made up of a number of pairs of parallel bars 15, each'pair of 4bars having bearing rollers 16 j ournaled between them, the rollers arranged in two rows, with the rollers of one ,row

staggered relatively to the rollers of the adjacent row. Ajconveyer 17, for feeding the lumber Vfrom the saw mill as the lumber` iscut from the timber, is shown to incline upwardly toelevated side of the4 bypass or slide, the inner terminus of the conveyer being located a slight distance above the elevated end of the slide and spaced therefrom to leave a substantial gap 18 between them, through which ,the lumber is adapted to drop under certain conditions, as hereinafter explained. The conveyer is preferably in the nature of a series of chains 19 arranged side by side at suitable intervals and passing over sprocket wheels 20, which are secured to a shaft 21, journaled at the head of the supporting framework, this framework, as best shown in'Fig. 1, embodying a longitudiv nally-extending beam arranged directly un- Ward that side of ,the tank adjacent to the chains 19 pass over sprocket, wheels 22, se-

cured to an idle shaft 23 arranged `a substan- `tial distance below the shaft'2l, the chains thence passng-throughthe tanklunderneath the submerging lroller 12 and thence out of the tank to the point of discharge, and return by a suitable route back to the saw Inill.

`At the head of the' slidelli, a rock sha 2-1 is supported, having a number of 1 attached skids or ingers 25 adapted to seat on the ends ,of the longitudinal beams `of the i conveyer `and bridge the.` gap 18, the fingers or skids `when `in this "position formlng a continuous passage from` the conveyer to the slide 14, whereby the lumber is -lfed over the said tank and discharged on the conveyer chains at the lower end of the slide or by-pass. At the head of the slide or byfpass a stationary chute or skid inclines downwardly and inwardly underfthe gap 18 and is composed of the curved fingers 26, the skid discharging on the conveyer chains between the idle or guide sprocket wheels 22 andthe submerging roller 12.

The shaft 24, to which the fingers or skids 25 are attached, is extended beyond one end of the tank, where it' is provided with an attached arm 2'?, the same being operatively connected, as .shown in Fig.A 3, with a bellcrank lever 28, by a link 29, the bell-crank lever being arrangedbelow the arm at or near the elevation of the tank, and in turn connected to a second bell-crank lever 30, by a link 31. To the opposite arm of the bell-crank lever 30 is operatively connected a foot-actuated member 32, projecting above a platform 33, on which the operator or grader stands in determining the character of the lumber passing" up the conveyer 17. The bell-crank lever 28 is constructed as shown in Figs. 4, 5 and 6, wherein it is shown that the arms are separately made, with the arm to which the link 29 connects,

adapted to swing `upwardly relatively lto the other arm, but limited in its relative movement in the opposite direction by a stop 28a. By reason of thisconstruction of the lever L 28, shoulda piece of lumber become tangled v with the' theskids 26, from whence ngers, as when the fingers are in the dottifd position shown in F 3, the ngers are adapted to swing completely over point downwardly` along the slide 14,4

and

whereby ,the engaged lumber is adapted to escape. I p

The skid fingers 25,*bridging the gap 18 in the normal position of the parts, stand closed, as shown. in Figs. 1 and 2, and in full lines in Fig. 3; The operator or grader standing on `the platform 33 in observing a piece' yof lumber which should be passed through the soda bath,depresses the treadle or foot-actuating member 32,v as the said piece reaches the head of the conveyer, lifting the skid fingers 25 tothe dotted position shown in Fig. 3, whereupon the lumber in passing from the conveyer drops down on it slides onto the conveyer chains below and travels through the soda bath in vr'the tank, the lumber being submerged in the bath as it passes under the roller 12, In this way the vtravel' of the lumber through the soda solution or over the' by-'pass is controllable at the`will of the of the short straw or loblolly pine needs dipping,fwhereas a small per cent. of the lorgI-lea-f pine ordinarily need be treated.

aving thus described my invention, I

claim as new and desire to'seoure by Letters Patent:l i
